FBI: if we tell lies to a FISA Judge and he approves it, it's the truth.

Shen followed with another broad, all-encompassing question about the propriety of the FBI and DoJ’s behavior: “Are you aware,” she asked Priestap, “of any instances where the FBI or DOJ did not present what constituted credible and sufficient evidence to justify a FISA warrant?”

Priestap’s response is a textbook case of circular logic: “If it's not justified, the court doesn't approve it. So, like, if we're not meeting the standard required by the Foreign Intelligence Surveillance Court, the requests are turned down.”

“So, in other words,” said the Democratic counsel, “by definition, if you presented information and a FISA court approved it, that would constitute credible sufficient information?”

“In my opinion,” said Priestap, “yes.”

Sit back and savor that exchange for a moment. One of the most senior officials in the Federal Bureau of Investigation – an organization that regularly refers for prosecution people who don’t tell the full truth – champions this peculiar standard of credibility: If you can snooker a FISA court judge, the information used to traduce the court is rendered by definition “credible sufficient information.” What is the condition of the FBI if its leaders think whatever you can get past a judge is good enough?
